Hi Brett,
Currently there is no way to have a 10 lines textbox not push down the other fields. I will bring this up as a suggestion in our group meetings and if it's a viable feature you could see it somewhere down the road. To get some padding between cells what I normally do is use 5 columns and leave the middle column blank, another option is to add some spaces to the front of the field's caption for example ' Legal Notes', however since your Caption location is Top the latter suggestion will not work.
